zookeeper中每天都有timeout的报错

超时随着业务多了起来，超时也多了起来。没有业务的时候好像没有超时

感觉像是连上来以马就超时了一样

我把5台机器里的超1小时以后的超进找出来
09:02:45,649
09:07:49,434
09:12:53,758
09:17:57,563
09:23:01,415
09:28:05,307
09:33:09,181
09:38:12,959
09:43:17,034
09:48:20,896
09:53:24,488
09:58:28,532
感觉像是每5分钟一次。又有点像是kafka的一个管理工具KafkaEagle
但这个超时时间又和我的消费端的程序是一样的

kafka eagle是整点取数据，类似
10:00:00,630
10:05:00,630
10:10:00,630
10:15:00,630
10:20:00,630
10:25:00,630
10:30:00,630
10:35:00,630
10:40:00,630

设成tickTime=15000
现在没有这样的报错了
